NAILING-MACHINE.

i SPECIFICATION forming part of Letters Patent No. 635,181, dated October 1*?, 1899.

Application led March 11,1898. Serial No. 673,489, (No model.)

T0 all whom t may concern:

Be it known that I, SAMUEL Y. PnNRoD, a citizen of the United States,'residing at Choteau, in the county of'Teton and State of Montana, have invented certain new and useful Improvements in Nailing-Maehines, of

which the following is a full, clear, and exact specification.

My invention is an improved nailing-machine designed especially'for use in nailing shingles on roofs; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is aside view of my machine. Fig.. 2 is a partial elevation of the opposite side from that shown in Fig. 1. Fig. 3 is a sectional view on about line 3 3, Fig. l. Fig. 4 isa sectional View on about line 4 4, Fig. l. Figs. 5 and 6 are sectional views, respectively, on about lines 5 5 and 6 6 of Fig. l. Fig. 7 is a detail plan view of the discharge end of the machine. Fig. 8 is a detail section on about line 8 8 of Fig. 7, and Fig. 9 is a detail view of the rammer or hammer bar. Fig. l0 is a detail perspective view showing the cover for the nail-chute, and Fig. l1 is a detail cross-sectional view showing such cover.

My machine is designed to be held by the operator in one hand While it is operated by the other hand and includes a suitable framing provided with bearings for the nail-holding cylinder A, which is provided with a ratchet-wheel A', stopped by a detent-pawl A2, and operated by a pawl A3, which is actuated by the rammer or hammer bar B, which is reciprocated longitudinally in the framing.

In the construction shown the pawl A3 is actuated in one direction by a spring A4 and in the other direction b v a cam-surface B n the rammer, which surface is engaged by the end of the pawl A3, so such pawl will be moved longitudinally at each return stroke of the rammer. By thisconstruction the nail-holder A is partially turned with each stroke of the rammer to effect a discharge of the nails to the guide-chute, by which they are directed to the driving devices.

The nail-wheel A has its rim narrowed and provided with discharge-openings C, spaced apart to prevent a too-rapid feeding of the nails, which drop from such openings C as the holder is turned into the inclined feed-chute VD, which has at its bottom the longitudinal nails,so the latter when dropped into the feedchute D will automatically adjust, as shown in Fig. 3, with their shanks lying in the slots D/ and their heads overlying the Walls of such slot, as will be understood from said Fig. This chute D lies below the Wheel A, and a supplemental chute E discharges onto the said chute D and extends up alongside the periphery of the wheel A for the purpose of preventing ltoo great a drop of the nails, which may be discharged before the holes O reach theirlowermost position. Thissupplemental chute E may be arranged as shown in Fig. l and have its framing adapted at E to form a handhold to be grasped by the operator.

The wheel A may have a suitable feed-door a, secured by a hook or other suitable latch, so the wheel maybe filled with nails when desired.

The framing is provided with a nail outlet or orifice at F, through which the nails are driven into the shingles by means of a plunger G, which is struck by the lower end of the rammer B, or, where desired, the plunger G may be omitted and the rammer be supplied at its lower end With a shank to operate directly against the nails, as will be understood from Fig. 9. The nails, passing down the feedchute D by gravity, pass into a connectingchannel H, which leads to the discharge-outlet F, and in order to supply the nails singly to the driving devices I provide a separating feeding device I, which is operated by the hammer-bar and feeds the nails one at a time to position for operation by the driving device, one nail being dropped for each hammerstroke of the rammer. This feeding device I is preferably a plate operating across the feedchute D and provided with an opening I to receive lthe nails and a point I2, which passes between the nail to be discharged and the next plate I and arranged at its other end to be .op-

erated bya cam J on the bar B, the lever be- IOO ing operated in the opposite direction by a spring J2. The operation of this construction will be understood from Fig. 4.

To prevent the feeding of the nails when the feed-chute is full, I provide means for throwing the feed-pawl out of operation at such time. This is effected byproviding such pawl A4 with a projection afl, which extends into the feed-chute D above the position occupied by the head of the nail, so the nails when fed into the chute up to the said pawl A4 will extend beneath the projection a4 and hold the pawl A4 in its uppermost position, so it will not be operated by the further movements of the rammer until the nail has passed from beneath the projection a4, which will readily result from the jarring of the lnachine by the operation of the ram mer when the chute empties.

A leather or other suitable pad K may be provided to reduce the shock of the driving stroke of the rammel'.

My invention will be found especially useful in shingling, as byit a workman can drive the nails about twice as fast as with a hammer and can shingle in cold weather, when the necessity of wearing gloves makes it practically impossible to handle shingle-nails.

In Fig. lO I show a hinged spring-actuated cover Z for the lower end of the nail-chute to prevent the nails from jumping out of the chute from the rebound as they strike the lower end of such chute.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a nail-driving machine the combination of the feed-chute, the nail-holding Wheel arranged vertically edgewise over the feedchute, and the supplemental chute extending over the feed-chute and lying partially between such chute and the wheel, the feedehute and supplemental chute being extended in the same plane with the wheel and with each other substantially as set forth.

2. In a nail-driving machine the combination of the framing having the feed-chute, the nail-holding wheel having openings by which to discharge the nails to such chute, the operating-pawl for turning such wheel, the rammer arranged to operate said pawl, and devices whcreby the pawl will be held from operation by said rammer when the feed-chute is full of nails, substantially as set forth.

3. The com bination of the framing, the nailholding wheel,tl1e feed-chute arranged to receive nails from said wheel, the rammel', and the pawl arranged for operation by the rammer and adapted to turn the wheel and provided with a portion projecting into the feedchute in position to be engaged by nails fed in such chute, substantially as set forth.
